This report considers one of the stages of work on the development of a series of superconducting magnets operating at temperatures up to 65 K for the possible creation on the basis of a series of accelerators: proton cyclotron (Phasotron) , medical cyclotron (SC230 with HTS winding, 4kA, 2-T) and etc.

An ionizer of the MaMFIS type (Main Magnetic Focus Ion Source) [1] produces ions with a high charge in local ion traps of a pulsating electron beam, where the density can still reach extremely high values (~10 kA/cm2). X-ray radiation from Bi60+ ions was detected. The peculiarity of the ionizer – a high ion charge and a relatively low number of ions, makes it attractive for experiments with an ion Penning trap (MATS and LaSpec: High-precision experiments using ion traps and lasers at FAIR).

The experiments were carried out within the framework of the project «Energy and Transmutation of Radioactive Waste». The decay of nuclei under the action of laser radiation with a wavelength of 1064 nm on their aqueous solutions was studied. The well-studied 152Eu nucleus is of particular interest.
